LIQUID-DISPENSING DEVICE.

To all whom it may concern. v

lie it known that I, Man'rm O. Hoornse, a citizen of the United States, residing in flhiladelphia, Pennsylvania, have invented certain Improvements in Liquid-Dispensing '.Devices, of which the following is a spe-citication. i

Une object otl my invention is to provide a container', particularly designed for holding liquid soap or other substance, with a relatively simple, inexpensive, and substaw tial device whereby a limited and predetermined quantity ot liquid may be delivered Al'roni said vessel at will; the construction being such that the delivery ot the liquid is certain and rapid. I also desire to provide a liquid dispensing device with a measuring valve, of such construction as to not easily be put out ot order or require attention, whereby it shall be possible to secure at will a predetermined amountl o't liquid troni the reservoir connected to said valve; the construction including means whereby the valve is normally held in and tends to return to, a definite position.

These objects and other advantageous ends I secure as hereinafter set t'orth, reference lot-Pingl had to the accompanyingdrawings, in which Figure '1.,' is a vertical section ot a liquid soap dirqurn.. ng device constructed according to my invention; Fig. 2, is a fragmentary vertical section ot" one portion of the apparatus shown in Fig. 1; certain of the parts being illustrated as turned to a position in which a measured quantity ot liquid is delivered; Fig. 3, is a horizontal section on the line {jr-(z, Fig. l and Fig. 1l, is a vertical section ot' a modified form ot my invention.

'ln Figs. il. to ot the above drawings, 'l represents a reservoir or containing vessel which is preferably ot glass and provided at its upper end with a relatively small inlet openingl At its lower end this vessel is provided with a contracted neck 3 attached in any desired manner to a valve easing tgiu the present instanee by being threaded into the same. A liquid tight joint is se cured between the parts by use of a gasket or body of packing 5. The valve easing is provided with a downwardly Ytlared chamber in which is revolubly mounted a conical plug valve 6, whose lower end projects beyond the valve easing and is m'ovided with an Specification of Letters Patent.

operatingr arm 7. Said vali e held in position in the valve casing by means ot a spring 8 mounted on a stud 8 fixed in the valve and having a head S". This head is held in any adjusted position on the stud by a set screw, and the spring has one end tixed to said head while its other end is held to the valve casing, though the lower end of the spring rests on a washer 8' in turn supported on the valve casing.

rlhc valve casing is [novided with two passages ot" which the first is indicated at t) and extends trom the interim' ot the container l, to the 'alve chamber in said easing. The second passage is indicated at l() and the valve structure (i has a cavity l2 so placed as to be capable ote communicating either with the lower cnd ot the passage t) or with the upper end ot' the passage l() in the valve casing, aud there is in addition in said valve a second passage i3, capable ot being brought into cdmmunication withthe passage. l() of the casing and having an outlet opening on the lower endet the. valve. ln addition there is an air passage 'll extending through the wall o't` the `valve cas ing and so placed as to be brought into oommunication with a second air passage 12 connected to the cavity l2 ot' the valve when this latter connects with the passage l0. Two stops ll and l5 are provided on the lower edge of the valve casing 4 in suoli positions as to limit to any desired extent the movement of the operatingr arm 7`v and therefore oli the valve to which it is fixed, so that when said handle is in the position shown iu Fig. l, the cavity l2 of the valve is in conm'iunieation with the passage t) of the valve casing and therefore receives a definite charge ot liquid soap or other material from the interior of the reservoir l. Vixen by means of the arm 7, the valve is so turned that said arm engages the stop 14, the charge of liquid within the cavity l2 of the valve passes into the cavity 10 ot' the cas-4 ing ll, which action facilitated by reason ot the tact that air admitted to the upper part of said cavity l2 through the air passagcsll and l2, From the cavity l0, the

liquid is tree to flow into the passage 13 in the valve, 'from which 'it escapes for use in the well lmown manner. The construction shown is oi. suchdesign that the spring draws the valve upward into its chamber and also tends to return it to the. position shown in Fig. 1, when it is moved there. from. In that form of my invention shown in Fig. 4, the valve has connected to it a spindle 17 extending upwardly through the reservoir 1a and through a cap or cover 1b. The upper end of said spindle is provided with a knob or handle 18 whereby it, with the valve 6a, may be turned, and there is a vfor the reception of the valve 6a, in such position as to communicate with the cavity 12 of the valve. Said casing also has a second cavity 10a capable of communicating with the cavity in the Valve when the latter has been turned to the predetermined extent from the position shown, alt-hough in such case this second cavit-y is open at the lower end tov permit of the direct discharge of liquid entering it. Undernormal conditions the cavity in the valve is illd through the passage 9a with the liquid in the reservoir, and when, by means of the handle or knob 18, the valve is turned sufficiently, this cavity of the valve is brought into communication with the passage 10a into which its liquid is discharged and from which it flows out. As soon as the handle is released, the spring 19 automatically returns the valve 6a to its normal position shown. By providing the air vent 11 for t-he cavit-yi12, in that form of my invention shpwn in Figs.

lv and 2, any possibility of the charge of liquid remaining in said cavity instead of 4passing out through the channel 13 is same and provided with a valve chamber,`

there being a passage in the casing extending downwardly from the bottom of the reservoir and opening into the upper part of said chamber; a valve in the chamber having a cavity opening in its side so as to be capable of connecting with the passage in the casing, said valve also having a passage opening on its side and forming an outlet at its bottom, there being a cavity in the side of the valve chamber placed to simultaneously communicate with the cavity and the passage of the valve; with means for turning said valve.

2. The combination of a reservoir; a valve casing mounted on the .lower end of said reservoir and having an upwardly tapering valve chamber; a valve in said chamber for controlling the delivery of liquid from the reservoir and provided with an upwardly extending stem; a helical spring on the stem acting between the same and the casing to retain lthe valve tightly in its chamber and connected to oppose rotation of the valve; with means for turning the valve.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
